Machine Gun Kelly and Fifth Harmony's Camila Cabello are set to release their new joint single "Bad Things" on Friday, and Billboard has the exclusive first look at the cover art.

The cover features a set of lips adorned in flowers over a blue background. No word yet on the song's sound or whether it will end up on a new album from MGK or Cabello.

See the art for yourself:

The song is the second venture for Cabello outside Fifth Harmony: She previously collaborated with Shawn Mendes on the 2015 single "I Know What You Did Last Summer," which hit the Billboard Hot 100 top 20.

This is the first new song from MGK since the release of his 2015 album General Admission.

UPDATE: After we published this story, Machine Gun Kelly and Camila Cabello both tweeted handwritten lyrics from the song. MGK tweeted, "I want you forever even when we're not together/ Scars on my body, I can look at you whenever," while Cabello shared, "Am I out of my head? Am I out of my mind?"
